A Nonparametric Approach for Assessing Goodness-of-Fit of IRT Models in a Mixed Format Test     

Tie Liang  Craig S. Wells 《教育实用测度》2015,28(2):115-129

Investigating the fit of a parametric model plays a vital role in validating an item response theory (IRT) model. An area that has received little attention is the assessment of multiple IRT models used in a mixed-format test. The present study extends the nonparametric approach, proposed by Douglas and Cohen (2001), to assess model fit of three IRT models (three- and two-parameter logistic model, and generalized partial credit model) used in a mixed-format test. The statistical properties of the proposed fit statistic were examined and compared to S-X² and PARSCALE’s G². Overall, RISE (Root Integrated Square Error) outperformed the other two fit statistics under the studied conditions in that the Type I error rate was not inflated and the power was acceptable. A further advantage of the nonparametric approach is that it provides a convenient graphical inspection of the misfit.  相似文献   

A Neo-Kohlbergian Approach: The DIT and Schema Theory   总被引：2，自引：0，他引：2  

James Rest  Darcia Narvaez  Muriel Bebeau  Stephen Thoma 《Educational Psychology Review》1999,11(4):291-324

Macromorality concerns the formal structure of society, as defined by institutions, rules, and roles. Micromorality concerns the particular face-to-face relations that people have in everyday life. Kohlbergian theories are most useful for issues of macromorality. The Defining Issues Test (DIT) derives from Kohlberg's approach but makes several departures, including defining cognitive structures in terms of schemas instead of stages, reformulating the definition of postconventional moral thinking, and using different research strategies. The validity of the DIT is based on seven criteria (briefly discussed), and hundreds of studies have produced significant trends. Recent research derived from schema theory produces novel phenomena that link our theory of moral schemas more closely with information processing and decision making.  相似文献

Determinants of Study Progress: The Impact of Student,Curricular, and Contextual Factors on Study Progress in University Education     

Adriaan Hofman  Muriel Van Den Berg 《Higher Education in Europe》2000,25(1):93-110

The subject of this research is the impact of student characteristics, curriculum, and contextual factors on the careers of students in university education in The Netherlands. A theoretical model including various measurements of these factors was evaluated by means of linear structural equation modelling. Students in the ‘prestatiebeurs’ (performance scholarship) system, which requires a shorter nominal duration of a given study programme, achieve better results compared to those in the ‘tempobeurs’ system, which allows more study time. Women make better progress in their studies than men do. Students in technical education obtain fewer study points than others, even though they spend more time studying and have earned better grades in secondary school. In general, paid work during higher education has a negative effect on study progress, while the amount of time spent studying has a stronger influence on the study progress of men than of women.  相似文献   

“Intermediate” Concepts and the Connection to Moral Education     

Muriel J. Bebeau  Stephen J. Thoma 《Educational Psychology Review》1999,11(4):343-360

This paper provides a brief overview of Rest's (1983) conception of the important processes that contribute to effective moral decision making, summarizes efforts to design and assess moral education programs based on Rest's Four-Component Model, and describes new directions in the assessment of moral judgment development that are specifically directed toward professional ethics education. Based on preliminary studies, we recommend that, in addition to measuring each of the processes in Rest's model, educators design profession-specific measures of moral concepts that better reflect the content of professional ethics education. Labeled intermediate concepts measures, these assessments attend to concepts that are more specific than the abstract moral schemas tested by Kohlbergian measures of moral judgment and more general than concrete codes of professional ethics.  相似文献   

Spatial Abilities Training in Anatomy Education: A Systematic Review     

Jean Langlois  Christian Bellemare  Josée Toulouse  George A. Wells 《Anatomical sciences education》2020,13(1):71-79

Spatial abilities have been correlated to anatomy knowledge assessment and spatial training has been found to improve spatial abilities in previous systematic reviews. The objective of this systematic review was to evaluate spatial abilities training in anatomy education. A literature search was done from inception to 3 August 2017 in Scopus^® and several databases on the EBSCOhost platform. Citations were reviewed and those involving anatomy education, an intervention, and a spatial abilities test were retained and the corresponding full-text articles were reviewed for inclusion. Before and after training studies, as well as comparative training programs, relating a spatial training intervention to spatial abilities were eligible. Of the 2,405 citations obtained, 52 articles were identified and reviewed, yielding eight eligible articles. Instruction in anatomy and mental rotations training were found to improve spatial abilities. For the seven studies retained for the meta-analysis that included the effect of interventions on spatial abilities test scores, the pooled treatment effect difference was 0.49 (95% CI [0.17; 0.82]; n = 11) improvement. For the two studies that included the practice effect on spatial abilities test scores in a control group, the pooled treatment effect difference was 0.47 (95% CI [−0.03; 0.97]; n = 2) improvement. In these two studies, the impact of the intervention on spatial abilities test scores was found despite the practice effect. Evidence was found for improvement of spatial abilities in anatomy education using instruction in anatomy and mental rotations training.  相似文献   

“Well,You Can’t Force Them”: Altercasting in the Home Health Care Context     

Peggy S. Kendall  Muriel Scott  Krista Jolivette 《Communication Studies》2019,70(1):99-113

Home health aides are often low-paid, low-status workers, performing their job in an isolated and interpersonally complex environment. This study, made up of semistructured interviews with 36 home health aides, explores compliance-gaining challenges faced by “low status, remote workers.” It was found that altercasting, a compliance-gaining technique using social roles to govern behavior, is well suited for the home care context. Aides were found to activate four altercast roles, including parent, trainer, employee, and friend. It is suggested that by using positive altercasting as a compliance-gaining technique, aides are able to both persuade their client to complete necessary tasks of daily living at the same time they construct and maintain the moral identity of a good caregiver.  相似文献

Teaching cell and molecular biology for gender equity     

Sible JC  Wilhelm DE  Lederman M 《CBE life sciences education》2006,5(3):227-238

Science, technology, engineering, and math (STEM) fields, including cell biology, are characterized by the "leaky pipeline" syndrome in which, over time, women leave the discipline. The pipeline itself and the pond into which it empties may not be neutral. Explicating invisible norms, attitudes, and practices by integrating social studies of science into science education may be the necessary first step in helping female students persist in STEM disciplines. In 2003 and 2004, a sophomore Cell and Molecular Biology course at Virginia Tech (Blacksburg, VA) was taught integrating social studies of science with standard material. The course was successfully implemented, teaching students factual content while increasing awareness of the cultures of science and their self-confidence in engaging with the subject. Course evaluation data indicated that females in particular perceived greater gains in logical thinking and problem-solving abilities than females in a traditional cell biology course. Consistent with K-12 studies, males in this class were likely to view scientists as male only, whereas females viewed scientists as male and female. This pilot project demonstrates that social studies can be integrated successfully in a cell biology course. Longitudinal studies of this cohort of students will indicate whether this approach contributes to the retention of women in the field.  相似文献
